Call Scenarios and Applications

Issue  7 March 1998

In call sequence 1, a service observer is added to the call using Single-Step

 

Conference. The observer is first added in a listen-only mode, using Single-Step 
Conference with no visibility. The observer is later connected in a listen/talk mode 
by disconnecting the observer and doing a second Single-Step Conference with 
full visibility.

State or national laws may require you to inform the parties on a call that the 
call is being monitored.

Just prior to the messages shown, the application learned (via domain control on 
station 3001) that a call with CID 17 has alerted at station 3001 and has been 
answered. The application knows that the station 3010 wants to service observe 
any call that arrives at this station.
